MACHINERY FOR MANUFACTURING BOTTLES.

SPECIFICATION forming part of Letters Patent N 0. 647,352, dated April 10, 1900. Application filed April28, 1899. Serial No. 714,929- (No model.)

To all whom it may concern:

Be it known that I, ROBERT PICKREN WOODILL, a citizen of the Dominion of Canada, residing at Winnipeg, in the Province of Manitoba and Dominion of Canada, have invented new and useful Improvements in Machines for theManufaoture of Bottles, of which the following is a specification.

My invention relates to machines for finishing the necks of bottles-t. e., forming heads upon and smoothing the same. It contemplates the provision of a machine in which a oenteringguide and a filler revolving in one direction operate in conjunction. with dies revolving in the opposite direction, the direction of movement of the guide and filler and the dies being automatically reversed about every two and a half revolutions, whereby twisting of the necks of bottles is prevented and a perfectly-smooth {finish thereof is attained. 7

Other advantageous features of the invention will be fully understood from the follow ing description and claims when taken in conjunction with the annexed drawings, in which- Figure 1 is a vertical longitudinal central section of my improved machine with some of the parts in elevation. Fig. 2 is a top plan view. Figs. 3 and 4 are sections taken in the planes indicated by the broken lines 3 3 and 4 4, respectively, of Fig. 1. Fig. 5 is a detail transverse section taken in the plane indicated by the broken line 5 5 of Fig. 1. Fig. 6 isa detail side elevation illustrating one of the die-carrying jaws and the die thereon, together with the complementary lover of said jaw and the spring interposed between the two. Fig. 7 is a perspective view of one of the die-carrying jaws and the die thereon. Fig. 8 is a transverse section taken in the plane indicated by broken line 8 8 of Fig. 2.

In the said drawings similar letters designate corresponding parts in all of the several views, referring to which--- A is the bed of my improved machine, which is preferably of the general shape shown and is mounted upon legs B.

O is a transversely-disposed drive-shaft, which is journaled in standards a, rising from bed A and is equipped with a band-pulley b,

a grooved pulley 0, two gear-wheels d, and a pinion e.

D is a longitudinally-disposed shaft which is journaled in a standard f, rising from the bed A, and is provided with a fast frictionwheel g, bearing a rubber annulus h. Said shaft is also provided with a centering-guide z' and a filler or filling-flange the latter being preferably formed integral with the guide, which is screwed on or otherwise fixed to the shaft, so as to turn therewith.

E is a tubularshaft or sleeve loosely mounted on the shaft D and journaled in a standard is, rising from bed A. This sleeve is provided with a fast friction-wheel Z, having a rubber annulus m, and is also provided with a loose and endwise-movable cone n, the purpose of which will be presently explained.

F F are jaws fnlcrumed in brackets 13, extending laterally from the forward end of the sleeve E.

G G are dies which are detachablyconnected by screws or other suitable means to the jaws and are designed, in conjunction with the guide 6 and filler j, to form a head on a bottle-neck.

H H are levers fulcru med at their forward ends in the brackets p and having antifriction-wheels g at their rear ends, designedto engage the cone n.

I I are transverse springs which are interposed between and connected to bars 0' at the rear ends ofthe levers H and are designed to hold the wheels (1 against the cone n, and J J are coiled springs interposed between the adjacent ends of the jaws and levers and having for their purpose to yieldingly press the dies on the former against the bottle-neck that is being operated on.

By virtue of the construction thus far de scribed the shaft D, together with the guide i and filler j, may be rotated in one direction, and the tubular shaft or sleeve E and its appurtenances may be simultaneously rotated in the opposite direction. The cone nis also free to bemoved endwise, forward, andbackward. When the shaft D is rotating in one direction-and the shaft or sleeve E in the opposite direction and the cone n is moved forward to press the diesGagainsta bottle-neck mounted on the guide it, the filler j operates to press the glass at the end of the bottleneck into the depressions of the dies, so as to form a bead and at the same time smoothes and finishes said end of the neck. The rotation of the dies G in one direction and the simultaneous rotation of the guide 2' and filler j in the opposite direction results in the quick formation of a head upon the end of a bottleneck and expedites the finishing of the said end. Such rotation of the parts mentioned in opposite directions tends, however, to twist the necks of the bottles operated upon. To overcome this objection, I- provide mechanism intermediate of the drive-shaft O and the shaft D and sleeve E, whereby said shaft D and sleeve E are simultaneously rotated in opposite directions and are reversed at he quent intervals. This mechanism comprises a transversely-movable slotted block J, which loosely receives the shaft D, arbors K, conj nected to said block and extending through standards 3, rising from the bed A, gearwheels L L, loosely mounted on the arbors.

K and having teeth intermeshed with those rings '15, of rubber or other suit-able material, a lever M, fulci'umed at an intermediate point of its length on a support it, rising from bed A, and having an angular arm '0 at its up- 1 per end (see Fig. 1) interposed between two lugs to on the block J, and a gear N, which is mounted on a shaft 00, arranged in standards y, rising from bed A. provided with teeth 2, which are intermeshed with those of the pinion e of drive-shaft C. It is also provided with two parallel peripheral grooves 2, designed to alternately receive an angular branch ct at the lower end of the lever M,a passage 1) connecting the parallal grooves, seats 0 c at opposite sides of said passage, and pivoted spring-pressed switches or switchpoints cl (1 which control the passage band have their outer ends normally arranged in the seats c,as shown in Fig. 3. The parts are shown in Fig. 5 with the lowerangular branch at of the lever M in the left-hand groove z of the gear Nand the friction-rin g t of the gear-wheel L in engagement with the friction-Wheels g and Z on the shaft D and sleeve E, respectively. From this it follows that when the drive-shaft O is rotated in the direction indicated by the arrow in Fig. 1 the shaftD and sleeve E will be rotated in opposite directions until the branch at of the lever M engages the switchpoint d and presses the same back into the seat 0 and passes into the right-hand groove .2 of gear N. When the said branch a of lever M takes the course mentioned, the said lever is rocked in the direction indicated by arrow in Fig. 5, with the result that the gear L is carried out of and the gear L is carried into engagement with the gears g Z, and the direction of rotation of both shaft D and sleeve E is reversed. Such latter movements The said gear is of the shaft D and sleeve E continue until the branch a of lever M is engaged and guided by the switch-point d back into the left-hand groove 2' of gear N, when the direction of rotation of said shaft and sleeve is again reversed. The frequent automatic reversing of the direction of movement of the shaftD and sleeve E serves, as stated, to prevent twisting of the necks of the bottles operated on and also serves to insure a perfectly-smooth finish of the ends of the bottles, which is a desideratum in this class of de- .Vices.

Fixedly connected to and depending from the cone 1?. is an arm n, which has its lower end shaped to engage aworm-screw 1;,screwed on or otherwise'fixed to a shaft 1", journaled in bearings at the under side of the bed A. The said shaft 4", and hence the screw 13, are rotated during the operation of the machine through the medium of a belt 3, which passes around the pulley c on the drive-shaft, under idler-pulleys t, and around a pulley u on shaft 1. In order to enable the attendant of the machine to move the arm n into engagement with the worm-screw p, and thereby of the gear-wheels d and also having frictioncause the cone to to move forwardlyand press the dies G against a bottle-neck on the guide 1', I provide the transversely-movable slotted plate 7;, which loosely receives the said arm n and is adjustably connected to the bed A, and means for shifting said plate. Such 1 means comprises a hand-lever w, a bell-crank lever 03, and a link .2 interposed between and connecting the hand and bell-crank levers, all as best shown in Fig. When the handlever 10' is released subsequent to the forward movement of the cone u, the cone and the parts connected with the same are re turned to their normal positions through the medium of a coiled spring 10 interposed between the arm n and one of the standards, as

shown.

For the purpose of enabling the machineattendant to readily take up slack of the belt 8 the shaft n bearing the idler-pulleys t, is journaled in a yoke 13 and passed through a slot 0* in a hanger s straddled by the yoke, and a screw '6 is mounted in the lower end of the yoke and arranged to bear against the hanger, as shown. By simply turning said screw the belt 3 may be tightened or loosened, as desired.

It will be noticed from the foregoing that the guide 1' may be readily removed from shaft D and the dies G may be readily removed from the jaws F to give place to larger or smaller guides and dies, according to the size of the bottle-neck to be operated on.

I have entered into a specific description of the construction and relative arrangement of the parts embraced in the present embodiment of my invention in order to impart a full, clear, and exact understanding of the same. I do not, however, desire to be understood as confining myself to such specific con-- 645,352 i i a struction of parts, as such changes or modifications may be made in practice as fairly fall within the scope of my invention.
